  FIG. 10 is an operation flow diagram of the digital broadcast receiving apparatus 300 after content storage when the activation information file 520 according to the second embodiment of the present invention is not stored in the digital broadcast receiving apparatus 300. (2) When the activation information file 520 is acquired from the data separation processing unit 312, the activation information file 520 is acquired from the real-time broadcast because the digital broadcast receiving apparatus 300 does not store the activation information file 520. In FIG. 10 (a), the broadcasting station sends the activation information file 520 in the “activation information file transmission” step S451, and then in the “latest information transmission process” step S452, the same as the “latest information transmission process” step S441. It can be implemented by processing.

  Up to this point, the method of using two display triggers and non-display triggers has been described. As another method, a description of display time is added to the display trigger or control information file 530, and digital broadcasting is performed only for the specified display time. This can also be realized by a method in which the receiving apparatus 300 displays the latest information. If the contents of the control information file 530 are described as part of the display trigger information, and the digital broadcast receiving apparatus 300 is controlled by the control method using the control information file 530 according to the description contents of the display trigger, only the trigger information 540 is obtained. But it is feasible.

  The digital broadcast receiving apparatus side is as shown in FIG. 10B. In the “start receiver application from the receiving channel start information file” step S471, the data separation processing unit 312 starts from the channel currently being received by the viewer. Using the acquired activation information file 520, the receiver application processing unit 317 presents an activation screen to the viewer. Of the contents of the activation information file 520, the “real-time information reception channel designation script” 521 is unnecessary because it has already been selected, but the other scripts 522 to 528 of the activation information file 520 are necessary.

  In the “start monitoring of designated trigger information in the received channel from the received channel control information file” step S472, a specific ES of the MPEG-TS designated by the script by API control in the “trigger number designation script to be monitored” 522 is set. The trigger ID 541 of the flowing trigger information 540 is monitored and the corresponding trigger is acquired.

  When the stored content is played back, the receiver application processing unit 617 presents a startup screen to the viewer, and from there, the stored content is played back by the viewer operation, so that the receiver application processing unit 617 reads the startup information file 820 ( 17), the startup information file 820 will be described in two ways: (1) when acquired from the storage processing unit 616 and (2) when acquired from the data separation processing unit 612.

  First, the operations on the broadcast station side and the digital broadcast receiving apparatus side when content is reserved for storage and stored are exactly the same as described with reference to FIGS.

  Next, operations on the broadcast station side and the digital broadcast receiving apparatus side when content is reproduced after content storage will be described.

  First, FIG. 17 shows a data structure used in the digital broadcast receiving apparatus 600 according to the third embodiment of the present invention. The accumulated file path list information 800, the accumulated content management information 810, the control information file 830, and the accumulated content information 850 are the accumulated file path list information 500, the accumulated content management information 510, the control information file 530, and the accumulated content of the second embodiment. The information is the same as the information 550, and the different information is the activation information file 820. An item different from the activation information file 520 of the second embodiment is a “file monitoring script” 822. Other items having the same name are the same as those of the activation information file 520.

  Next, FIG. 14 is an operation flow diagram of the digital broadcast receiving apparatus 600 after content storage when the activation information file 820 is stored in the digital broadcast receiving apparatus 600 according to the third embodiment of the present invention. (1) When the activation information file 820 is acquired from the storage processing unit 616, the broadcast station uses the control information file 830 and the control information file 830 in the “latest information transmission process” step S741 in FIG. Sends the latest information file necessary for display.

  FIG. 16 is an operation flowchart of the digital broadcast receiving apparatus 600 relating to transmission / reception of the latest information in the third embodiment of the present invention. The processing contents of the “latest information transmission processing” step S741 are as shown in FIG. 16A. In the “sending latest information file at the latest information display timing” step S781, the latest information files (control information file 830 and control information file 830). The character information file, image file, video file, audio file, etc. necessary for displaying the image on the screen are transmitted at the timing when the latest information is to be displayed. If there are multiple pieces of the latest information, the process is repeated for the number of times.

  The processing on the digital broadcast receiving apparatus 600 side is as shown in FIG. 14B, but is almost the same as FIG. 9B, and the different processing block is “the file update status of the specified path from the control information file of the storage processing unit”. Monitoring start ”step S763 and“ latest information reception processing ”step S766. The other processing blocks are the same as step S461, step S462, step S464, and step S465 of the same name in FIG. 9B.

  In step S763, which is a functional block different from that shown in FIG. 9B, “Start monitoring of the file update status of the specified path from the control information file of the storage processing unit”, the API control is performed by the “file monitoring script” 822 of the activation information file 820. The information file 819 of the file path specified by the script is monitored.

  “Latest information reception processing” step S766 is as shown in FIG. In the “receive latest information” step S791, the latest information file (character information file, image file, video file, audio file, etc. necessary for screen display using the control information file 830 or the control information file 830) is acquired. Accumulate in the real-time accumulation processing unit 614. In the “update latest information file” step S792, an update event is acquired from the accumulated update monitoring processing unit 620 at the timing when the designated file is updated by the API.

  In the “display latest information on storage / playback content screen” step S793, the “display operation script” 826 of the activation information file 820 is described in the file paths 833 to 835 from the contents described in the control information file 830 by API control. Using the stored data, a video with the latest information added to the stored content playback screen is created, and the screen switching processing unit 619 is controlled by the “screen switching script” 828 of the activation information file 820 to switch the screen. The latest information is displayed by using the control method 831 of the control information file 830 or the “character / image display position (start point / end point coordinates)” 832 in the first to fourth screen display examples shown in FIGS. Such screen display control is performed.

  Steps S791 to S793 are repeated each time the latest information is continuously received. In the “delete latest information from the storage / playback content screen” step S794, the “latest operation script” 827 of the activation information file 820 displays the latest latest information after the latest information has been displayed or after a certain period of time has elapsed. Switch the screen to the stored content playback video that has not been recorded.

  FIG. 15 is an operation flow diagram of the digital broadcast receiving apparatus 600 after content storage when the activation information file 820 according to the third embodiment of the present invention is not stored in the digital broadcast receiving apparatus 600. (2) When the activation information file 820 is acquired from the data separation processing unit 612, the activation information file 820 is acquired from the real-time broadcast because the digital broadcast receiving apparatus 600 does not store the activation information file 820. In FIG. 15 (a), the broadcasting station transmits the activation information file 820 in the “activation information file transmission” step S751, and then in the “latest information transmission process” step S752, the same process as the “latest information transmission process” step S741. It can be implemented by performing.

  The processing on the digital broadcast receiving apparatus 600 side is as shown in FIG. 15B. In the “start receiver application from the receiving channel start information file” step S771, the data separation process is performed from the channel currently received by the viewer. Using the startup information file 820 acquired by the unit 612, the application processing unit 617 presents a startup screen to the viewer. Of the contents of the activation information file 820, the “real-time information reception channel designation script” 821 is unnecessary because it is already selected, but the other scripts 822 to 828 of the contents of the activation information file 820 are necessary.

  In the “start monitoring of the file update status of the path specified from the control information file of the receiving channel” step S772, the “file monitoring script” 822 of the activation information file 820 indicates the file path specified by the script in the API control. The information file 819 is monitored. Thereafter, the processing from step S773 to step S775 is performed in the same manner as the processing block of the same name from step S764 to step S766.

As described above, according to the digital broadcast receiving apparatus 600 of the third embodiment of the present invention, the update status of the file designated by the API that controls the accumulated update monitoring processing unit 620 and the accumulated update monitoring processing unit 620 is further monitored. By switching the screen to the video with the latest information added to the stored content playback video at the timing when the specified latest information file is updated, the latest information is updated at the timing and period that the broadcast station wants to show. Can be presented to the viewer.
